what are specifications of ADC embedded in N5244? i am intrested to know how much bandwidth i can examine with N5244. how smaller the signal i can pic with this?
I am going to use it with your 118 option. in short what maximum i can get from ADC with 118 option.
Hi,
Here is the Spec sheet for the N5244A:
http://literature.cdn.keysight.com/litweb/pdf/N5245-90008.pdf?id=1712187&cc=US&lc=eng
All of the information regarding Dynamic Range and system performance is in there. I'm not quite sure which bandwidth you are referring to. If you are interested in the data acquisition rate of Option 118, that can be found here:
Best regards,

i could not understand well. if your IF is at 8.33MHz, .4MSamples/sec may not be enough to get complete picture. however, if your IF is at baseband level, then it will be sufficent to retrieve all information. may be i am confusing it with DSP. could you please attached some Fast-CW data perticularly with pulse mode?
I just want to reconstruct sinosidal wave at baseband or IF level. will this be possible with VNA using Fast CW?
The IF is fully digital in the PNA, so IF frequency is really just an artifact of the way we take data. The Dig IF frequency (imputed frequency of the NCO in the digital down converter) is changed as the IF BW is changed. The maximum IF BW is 15 MHz under normal circumstances (it can be increased to more than 30 MHz if you download the right DIF filters). But in fast CW mode you might consider the 15 MHz BW essentially the BW limit. At this BW, I think the DIF frequency is about 20 MHz or so, maybe a bit higher (I'd have to have one of the FW guys dig into the code to see for sure).
